It's not a stretch to say the world's tallest man is happy knowing he won't be growing any more.

The 8-foot, 3-inch Sultan Kosen has let it be known that he has finally stopped growing at the tender age of 29, according to IB Times.

The Guinness World Record Holder has held the title of the tallest living man since 2010, and actually grew a couple inches from the time he first made his mark. Kosen suffers from acromegaly, which caused his body to continually produce the growth hormone, The Hong Kong Standard reported.

The resulting stress on his body forced Kosen to use crutches to walk. However, things have been better since March, when he finally stopped growing thanks to a treatment at the University of Virginia that he started four years ago.

"Since I was tall, I faced obstacles in life. I had rough days. I couldn't get out of my room," he told ITN.co.uk. "My family had financial difficulties so I couldn't receive treatment. I was secretly crying in my room. I needed to burst out. It restricted my life. But ever since I have been certified by the Guinness World Records, my life has begun anew. I am very happy."

Guinness officials said Kosen is one of only 10 people in human history to grow beyond eight feet. He is the first 8-foot man to be measured in more than two decades.
